REAL TIME WITH... IPC APEX EXPO 2022 SHOW & TELL MAGAZINE I I-CONNECT007 125 Presenter: HongWen Zhang, Manager of Alloy Group, Indium What is the most interesting question that your IPC APEX EXPO presentation answers? The need for a low-mid-tem- perature solder, addressing the drop- shock-critical application without loss in TCT reli- ability. What is your answer to that question, and why? Durafuse LT and the second-gen pastes, reflowing as low as 190°C peak temperature, provide excel- lent drop-shock performance (at least comparable to SAC305 and two orders of magnitude superior to BiSn+) and the comparable TCT (-40/125°C) to SAC305. What is the most important piece of advice that have for your audience? For any applications of drop-shock-critical and low-mid-temperature-flow required, Durafuse LT will be the exclusive solder solution. It can be used for step-soldering following SAC soldering or directly for mainboard soldering to replace SAC305 pastes with reflow profiles of wide range of peak tempera- ture from 190°C to 245°C.
